Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a noise-reducing steam generator, and more particularly to an improvement of the thermally insulating heating chamber described in Japanese Patent Publication No. 55-43781.

The device described in Japanese Patent Publication No. 55-43781 has a double-walled heating chamber inside the container, and the water inside the container is kept at a low temperature to ensure safe evaporation even during the initial heating stage. be.

Furthermore, in the boiling prevention type steam generator described in U.S. Patent No. 3,714,392, the water in the container was kept at a low temperature in an attempt to prevent the boiling water in the container from being sprayed from the device, but it still did not prevent the spitting phenomenon. I couldn't do it.

The steam evaporated from the steam generator has the characteristic of emitting noise due to changes in the conditions in which the fluid flows out.
The present invention seeks to reduce or eliminate noise so that the user, a sleeping infant or other patient, can fall asleep more easily.

The muffled steam generator of the present invention has a discharge opening in the cap for discharging excessively generated steam even when the steam boils rapidly or when the liquid content decreases and the operation is terminated. This is a steam generator that is noise-free, low-temperature, and free of spitting. The said exhaust opening is to eliminate excessive boiling steam and unnecessary noise.

The discharge opening is communicated with a conduit provided in the inner casing of the heating chamber via a water passage hole in the inner lid and a pipe member. The inner lid is provided with an electrode extending into the heating chamber. A thermally insulating outer housing having a double peripheral wall is provided on the outside of the heating chamber. A heating mechanism formed by assembling the above-mentioned members is attached to a cap member and extends downward, and the cap member is disposed in an opening provided in the upper wall of the container.
An embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference number 10 generally indicates a steam generator according to the invention. The device 10 consists of a pair of members that can be easily assembled, and the pair of members form a container 12 consisting of a side wall 16 upright from the periphery of a bottom wall 14 and a top wall 18 extending from the side wall 16. A heating mechanism 22 is arranged on the wall 18 .

The heating mechanism 22 consists of four main members as shown in FIG. That is, it is assembled from a head cap 24, an inner lid 26, an inner housing 28, and an insulating outer housing 30.

The cap 24 has a body 32 with a wall 34 and a space at the front lower part of the steam outlet 36 for receiving the drug so that the ejected steam carries the drug with it.
are integrally cast. The spout opening 3
Excess steam and boiling water discharge openings 38 are provided on both sides of the
40 are drilled. The cap 24 is removably fixed to the inner lid 26 with screws 104 through a hole 42 formed in its upper surface.

The inner lid 26 is formed with a body 50 integrally cast with a peripheral flange 52 and is provided with a top wall 54 that aligns with the underside of the cap 24. The top wall 54 has a steam outlet 56 aligned with the outlet opening 36 of the cap and an outlet 5 aligned with the outlet openings 38, 40.
8,60 are provided. A pair of pipe members 62 and 64 communicating with discharge ports 58 and 60 are integrally formed in the body portion 50. Holding cylinder 6 for a pair of electrodes 70
6 and 68 are integrally formed with the body portion 50.

Both electrodes 70 are connected by known means to an electrical cord (not shown) used in each household. A notch 72 is provided in the peripheral flange 52 to align the members.
is provided, and a through hole 74 is drilled for assembling the components.

The electrode 70 extends into the inner housing 28 and depends into a reduced diameter heating chamber 80. The lower ends of the tube members 62, 64 of the inner lid are fitted into a pair of conduits 84, 86 vertically installed in a heating chamber 80 made of a heat insulating material. The lower ends of both conduits are open into the heating chamber.
As shown in FIG. 2, a bottom wall 88 of the heating chamber 80 is provided with an inlet hole 90 for inflowing outdoor water. A peripheral flange 85 of the inner housing 28 is provided with a notch 87 and a hole 89 that align with the notch 72 and hole 74,
This facilitates assembly of the members. still,
A protrusion 115 is provided on the outer peripheral flange 96 of the outer housing, and the protrusion 115 fits into each of the cutouts to arrange each member at a predetermined position. The pin 99 also fits into the hole in the gasket to position both members coaxially.

The outer housing 30 surrounding the heating chamber 80 is formed into a double wall with peripheral walls 92 and 94 made of an insulating material, and a plurality of screw holes 98 are bored in the upper ends of the double peripheral walls 92 and 94. A peripheral flange 96 is provided.

Gaskets 100 and 102 are interposed between the peripheral flanges 52 and 85 and between 85 and 96, respectively.

The screw hole 108 at the top of the inner lid has the screw hole 10
The inner cover and the cap are assembled and fixed by screwing together a pair of screws 104 through the holes 42 of the cap 24 that are aligned with the inner cover 8.

The peripheral flanges 52, 85, 96 are arranged in layers, and a plurality of screws 110 are inserted into the screw holes 98 by passing through the holes 74, 89 formed therein and the holes of the gaskets 100, 102 that are aligned with the holes. By mating, the peripheral flange can be integrally screwed and fixed.

As described above, once the components are fully assembled, the electrode 70 is extended and placed within the heating chamber 80. The water in the container flows into the heating chamber through the through hole 90 at the lower end of the heating chamber 80.

Then, the water in the heating chamber is heated by the electrode 70, and the generated steam rises and is ejected to the outside from the steam outlet 56. If the power used between the electrodes 70 increases excessively for various reasons, for example, an excessive amount of electrolyte (salt) is used contrary to the instructions, and more vapor than the preset amount is generated. When this occurs, the steam should be discharged from the steam exhaust ports 58 and 60, or
Alternatively, the pipe member 62 is forced to circulate through the through hole 95 formed in the bottom wall of the inner case 28 into the space between the heating chamber 80 and the inner circumferential wall 94 of the outer case. , 64 and the outlet opening 5
8,60 and is discharged to the outside. Such a safe arrangement prevents the boiling noise from being eliminated by the steam force through the spout opening 56 causing the steam force to have an excessive pressure.
